Blue lines and screen jittering after any linux boot
by guilhermicas from LinuxQuestions.org on (#5CRW4)
I can use my laptop fine, but my screen jitters a lot and shows weird lines.
It is not a hardware related thing, because if i boot from USB or even go to BIOS, the screen is normal, the moment the system starts linux, the screen goes black for some seconds and when it turns back on, the problem starts (Currently on Lubuntu, but this has happened to me on arch on this same computer before and i tried switching).
I have linux-firmware installed that should take care of the drivers, and my gpu seems to be detected correctly, but the screen just jitters.
I think the problem might be related to the bootloader or Grub not setting my gpu settings correctly or something like that.
I can reply with logs or images/videos if needed.
